Abstract

Abstract Inhomogeneity and impurity effects on the CDW are investigated in the one-dimensional conductor K 0.30MoO 3. Electric-field induced deformations of the CDW were found by x-ray experiments. The deformations are verified to be caused by an inhomogeneity of the electric field in samples. The time necessary to complete the deformation varies with temperature and the electric field. This characteristic ime is nearly equal to the relaxation time measured electri cally. In a sample where the electric field is inhomogeneous, it is indicated that a part of the CDW slides leaving others rest. The effect of impurity on the transport and the structural properties of K 0.30MoO 3 are investigated in rubidium or tungsten doped samples. X-ray diffraction experiments showed that the effect of the impurity doping on the CDW ordering in the transverse-direction is much larger than in the one-dimensional-direction.
